The present invention relates to a uniform fine powder continuous feeder, and more particularly, to a uniform fine powder continuous feeder having a coagulation preventive unit capable of forming a feed path while preventing scattering of powder when the powder scattered in the container is discharged to the outside To a continuous feeder.

In the present invention, the inner space of the container is divided into a storage space and a scattering space. After the powder stored in the storage space is supplied to the scattering space, a gas in the vertical direction is supplied to disperse the powder, To an upper portion of the space to allow uniform and quantitative supply of powders.

The present invention relates to a uniform fine powder continuous feeder equipped with an anti-aggregation unit capable of continuously feeding uniform powder while keeping the amount of powder supplied to the scattering space constant.

The present invention relates to a method for controlling the volume ratio of a scattering space and a storage space and for controlling the amount of powder supplied into the scattering space, Supply device.

The present invention relates to a uniform fine powder continuous feeding device provided with a vibration generating means and equipped with an anti-coagulation unit capable of more precisely controlling the powder feed amount in the scattering space.

In general, fine powders of a size of a few tens of micrometers or less adhere to each other due to electrostatic attraction to form agglomerates of larger size.

 Therefore, in the case of powder used for spraying and aerosol vacuum deposition, a usual method is to form a circular shape by granulating the fine powder so as to be able to supply quantitatively, thereby improving fluidity and supplying the powder through a micro tube or a hole Is used.

FIG. 1 is a SEM photograph of granular powder and granular powder, wherein granulated granular powder is formed in such a state that a large number of primary particles are weakly bound therein, and these granular powders gradually become large in size due to cohesive force, The flowability of the powder is deteriorated, and therefore it is difficult to carry the powder uniformly and continuously by a usual method.

Therefore, in the case of powders used for spraying and aerosol vacuum deposition, most of the powders are formed into a circular shape to increase the fluidity of the powders. Further, due to the addition of the granulation process, the powder is increased in price and the size of the powder is increased, There is a disadvantage in that it is required to be improved.

Particularly, in the case where an excellent coating layer such as an aerosol deposition coating method can be produced, quantitative control of fine powder feed is very important and the characteristics of the coating layer depend on the uniform supply and flow state of the powder, And the uniformity of the coating are also different, and it is very important to control them.

Accordingly, Korean Patent Laid-Open Publication No. 2001-0052900 discloses an apparatus for dispersing powder using ultrasonic vibration as shown in FIG.

However, the prior art has a limitation in supplying a large amount of powder, is not quantitative, and the dispersed powder eventually flocculates inside the conveying pipe, resulting in a problem that the amount of the supplied powder is uneven.

On the other hand, Korean Patent No. 10-1230241 discloses a technique in which a carrier gas is sprayed into a chamber as shown in FIG. 3 so that powder is scattered and scattered powder can be discharged through a transport pipe. No. 10-0916944 discloses a technique for providing a pressure gauge inside a transport pipe to check whether the flow rate and velocity distribution per hour of the aerosol are constant.

However, the above-mentioned prior art has a problem in that it is impossible to uniformly supply powder because the powder does not aggregate on the wall surface of the inside of the transport pipe responsible for the transport path of the aerosol.

In addition, the agglomerated powder agglomerates adhered to the inner surface of the transport pipe are separated from the inner surface by the air flow and flow together with the aerosol. In this case, there is a problem that a non-uniform deposition layer is formed as shown in FIG. 4

As shown in the drawing, the supply apparatus 100 according to the present invention stores a large amount of powder, scatters powder stored at the time of operation, forms an aerosol, and guides the powder to the outside (a device to be supplied with an aerosol).

The supply device 100 has a substantially cylindrical shape and is provided with a container 110 in which powder is stored. The side surface of the container 110 is covered with a cover 111.

And a power generating means 120 for generating a rotational power is provided on the upper side of the container 110.

The power generating unit 120 receives power from the outside to generate rotational power and the rotational power generated by the power generating unit 120 is transmitted to the inside of the vessel 110.

The upper surface of the container 110 is provided with an inlet 112 for selectively opening the inside of the container 110 and the powder can be supplied into the container 110 through the inlet 112.

Here, the powder is not limited in size and shape, and any powder can be applied as long as it can be scattered by wind power.

A gas guide pipe 113 is provided in the upper part of the upper surface of the container 110. The gas guide pipe 113 communicates with gas supply means (not shown) provided outside the vessel 110 to guide the gas supplied from the gas supply means into the vessel 110.

A powder discharge pipe 114 is provided on the rear side of the gas guide pipe 113. The powder discharge pipe 114 is configured to guide the powder that is scattered as the gas is supplied into the container 110 into the aerosol state to the outside of the container 110.

More specifically, the powder discharge pipe 114 is configured to discharge a part (relatively fine powder) of powder scattered inside the container 110 to the outside of the container 110.

A vibration generating means 130 is provided below the container 110. The vibration generating means 130 generates vibration and provides the vibration to the container 110. In the present invention, the vibration generating means 130 is configured to be adjustable within a vibration frequency range of tens to hundreds of Hz by adopting an electromagnet oscillator.

The powder discharge pipe (114) is connected to the coagulation preventing unit (200), which is a main component of the present invention.

The coagulation preventing unit 200 is for guiding a transport path of the aerosol discharged to the outside of the container 110 through the powder discharge pipe 114 and has a function of preventing the aerosol to be transported from being agglomerated inside.

The details of the coagulation preventing unit 200 will be described in detail below.

The detailed configuration of the supply apparatus 100 will be described below with reference to FIGS. 6 to 9 attached hereto.

FIG. 6 is a perspective view showing the internal structure of the continuous powder feeder 100 according to the present invention by removing the cover 111, FIG. 7 is a perspective view showing the internal structure of the continuous powder feeder 100 Fig.

FIG. 9 is a view showing a state in which the operation of the communicating part constituting the main part in the continuous fine powder continuous feeder according to the present invention is shown. Fig.

6 is a state in which the cover 111 is removed in order to explain the detailed structure inside the container 110 in more detail.

As shown in the figure, the container 110 has a storage space 115 in which powder is stored and a scattering space 115 in which the powder (P in FIG. 7) stored in the storage space 115 is continuously received and scattered. (Not shown).

That is, in the inside of the container 110, a partition plate 140 having a substantially V-shaped cross section is fixed upright.

The upper end of the partition plate 140 is fixed to the inner ceiling of the container 110 so as not to move and is configured to extend vertically downward so that the lower end of the partition plate 140 is adjacent to the inner bottom of the container 110.

Therefore, the partition plate 140 can divide the space inside the container 110 into the flared space 116 and the storage space 115.

Further, the partition plate 140 is configured to be able to adjust the angle of opening. This increases the volume of the fogging space 116 and the storage space 115. When the angle of the partition plate 140 is increased, the volume of the fogging space 116 is increased, The volume of the container is relatively reduced.

In the embodiment of the present invention, the fogging space 116 is configured to be adjustable in a volume ranging from 1/12 to 1/6 with respect to the volume of the storage space 115.

The end portion of the gas guide pipe 113 communicates with the inside of the scattering space 116, which is a limited space defined by the partition plate 140.

More specifically, the gas guide pipe 113 extends through the upper surface of the container 110 to the inside of the container 110. The lower end of the guide pipe 113 is close to the bottom surface of the container 110, The gas transferred in the downward direction through the pipe 113 is guided to be sprayed in a direction orthogonal to the bottom surface of the container 110.

In the present invention, the gas guide tube 113 has a substantially 'b' shape by bending a lower portion thereof, and a plurality of through holes are formed in the lower surface of the transversely bent portion to allow the gas conveyed along the gas guide tube 113 It is divided into a plurality of branches so as to be sprayed in the downward direction.

Therefore, the powder P existing in the bottom of the scattering space 116 can be uniformly scattered by the gas injected through the through holes.

A supply plate 150 is provided on the inner bottom of the container 110. The supply plate 150 has a disk shape and is configured to be rotatable by receiving rotational power from the power generation means 120.

The supply plate 150 serves to upwardly support the powder P stored in the storage space 115 and to supply the powder P of the storage space 115 to the scattering space 116 by a predetermined amount Concurrently.

That is, the supply plate 150 supports the powder P while maintaining a predetermined height in the container 110, and when the powder is rotated by the operation of the power generating means 120, And the powder P is supplied into the scattering space 116 by alternating the scattering spaces 116.

For this, a plurality of protrusions 152 are provided on the upper surface of the supply plate 150. The concavities and convexities 152 are formed to depress the upper surface of the supply plate 150 in a downward direction so as to have a step so that the powder P can be received therein.

Accordingly, the powder P contained in the concavity and convexity 152 can be supplied into the scattering space 116 when the supply plate 150 rotates clockwise (as viewed in FIG. 6).

In the embodiment of the present invention, the concavities and convexities 152 are formed on the upper surface of the supply plate 150 by a plurality of depressions 152, which are radially arranged at equal intervals.

However, various modifications may be made depending on the amount of the powder P to be supplied to the scattering space 116 or the size of the powder P.

For example, the concavity and convexity 152 may protrude upward from the upper surface of the supply plate 150, and may be formed in a plurality of points (cylinders) instead of the curves as shown in FIG.

Meanwhile, the center of the supply plate 150 is connected to a rotary shaft (reference numeral 122 in FIG. 7) so as to receive a rotational power from the power generating means 120.

The rotation shaft 122 serves as a rotation center shaft of the supply plate 150 and is axially coupled upwards in the up direction at the center of the supply plate 150. The upper portion is connected to the power generating means 120, Respectively.

The partition plate 140 may further include a blade 142 at a lower end thereof.

The blade 142 is configured to have a shape corresponding to the cross section of the partition plate 140 and is coupled to the lower end of the partition plate 140. The lower end of the blade 142 is connected to the supply plate 150, And may be extended to be in contact with the upper surface of the supply plate 150.

More specifically, when the lower end of the blade 142 is configured to be spaced apart from the supply plate 150 as shown in FIG. 7, the supply plate 150 is rotated by the blade P The powder P accumulated from the lower end of the supply plate 150 to the upper surface of the supply plate 150 can be supplied to the scattering space 116.

When the lower end of the blade 142 is in contact with the upper surface of the supply plate 150, the supply plate 150 feeds only the powder P contained in the unevenness 152 to the scattering space 116 .

Thus, the amount of the powder P supplied to the scattering space 116 can be adjusted according to the distance between the supply plate 150 and the blade 142.

On the other hand, a communicating portion 144 is provided at the upper end of the partition plate 140. The communicating portion 144 is for guiding part of the powder scattered in the scattering space 116 to the storage space 115 again.

Accordingly, if the powder scattered in the partition plate 140 is allowed to escape into the storage space 115, the communicating part 144 may be changed in various positions and sizes.

7, the communicating part 144 may be formed by cutting a part of the upper part of the partition plate 140 so that the fogging space 116 and the storage space 115 are communicated with each other.

At this time, the powder relatively large and heavy among the powder scattered in the scattering space 116 abruptly drops while the small and light powder floats to the upper part of the scattering space 116 and then flows into the storage space 115 through the communicating part 144. [ And is transported to the inside.

The powder discharged to the outside of the container 110 through the powder discharge pipe 114 can have finer and uniform particle size.

As another example of the communication part 144, a minute gap between the blade 142 and the supply plate 150 may serve as a communication part 144. [

In other words, in the scattering space 116, due to the action of the gas guide tube 113, the powders are scattered, but a vortex or the like may be generated due to the carrier gas injected at a high speed. Therefore, It can be difficult to keep.

Therefore, the uneven aerosol scattered inside the scattering space 116 can escape into the storage space 115 through the gap between the blade 142 and the supply plate 150, The resulting aerosols can become more uniform.

The communicating part 144 may be implemented in various sizes, numbers, and positions as long as the powder scattered in the scattering space 116 can be transferred to the storage space 115. In the storage space 115, It may be formed on the upper / lower portion or the center of the partition plate 140 considering the particle size of the aerosol to be transferred to the partition plate 140.

The powder discharge pipe (114) is connected to the coagulation preventing unit (200), which is a main component of the present invention. The flocculation preventing unit 200 has a function of forming a transport path to a place where an aerosol is required, and blocking the agglomeration of the aerosol during transportation.

That is, even if the aerosols dispersed evenly inside the container 110 are discharged through the powder discharge pipe 114, they may be agglomerated in the course of transportation along the transport path or may be agglomerated in the state of being attached on the path.

In this case, even if they are uniformly dispersed in the container 110, coagulation occurs during transportation, so that the dispersing ability of the feeding device 110 is reduced.

Therefore, the anti-flocculation unit 200 blocks the aerosols in which the powder is dispersed from being aggregated at the time of transportation, and by the action of the flocculation prevention unit 200, Can be obtained.

10 is a photograph of a glass substrate formed by using a uniform fine powder continuous feeder equipped with an anti-aggregation unit according to the present invention.

Hereinafter, the configuration of the coagulation prevention unit will be described in detail with reference to FIGS. 11 and 12 attached hereto.

One of the pair of connecting members 202 is connected to the powder discharge pipe 114. The connecting member 202 is connected to the powder discharge pipe 114. [

12, the anti-flocculation unit includes a tubular anti-coagulation tube 210 having an inner perforation formed therein, a vibration generator 230 positioned outside the anti-coagulation tube to generate vibration, And a protective member 220 for applying a restraining force to the flocculation preventing pipe 210 so as to contact the flocculation preventing pipe 210 while maintaining a predetermined position.

Although the cohesion prevention pipe 210 is made of a flexible material in the embodiment of the present invention, the cohesion prevention pipe 210 may be modified to have various materials, thicknesses, and lengths in consideration of the distance to the aerosol to be transported and the amount of transportation. Do.

The vibration generator 230 is configured to generate vibration by being supplied with power from the outside and is fixed adjacent to the outer surface of the cohesion prevention pipe 210, .

In the embodiment of the present invention, the vibration generators 230 are arranged on the outer circumferential surface of the coagulation preventing tube 210 so as to face each other, and a pair of the vibration generators 230 are disposed at predetermined intervals.

A power supply line 204 for power supply is provided outside the vibration generator 230, and all the vibration generators 230 are electrically connected to each other.

A protective member 220 is provided on the outer side of the vibration generator 230. The protection member 220 is configured to restrict movement while maintaining a state in which the vibration generator 230 is in contact with the outer surface of the cohesion prevention pipe 210. The protection member 220 may be used as various materials, It is preferable to simultaneously perform the role of restricting the movement of the user.

When the power is applied through the power line 204 and the vibration generator 230 generates vibration, the vibration is transmitted to the cohesion prevention tube 210, May be limited.

First, the powder P is introduced into the storage space 115 by opening the inlet 112 in the state shown in FIG. 6 (the cover 111 should be installed in FIG. 5). In this case, the inlet 112 is preferably located above the storage space 115, and the state before the powder P is introduced into the container 110 is as shown in FIG.

The gas guide pipe 113 is connected to the gas supply means (not shown) to be able to supply and receive a gas (argon, nitrogen, dried air, etc.) Unit 200 to be connected to a vacuum pump or a vacuum valve or the like of the aerosol supply object device.

When the preparation is completed as described above, the vibration generating means 130 is operated to provide vibration to the powder P in the container 110, so that the powder P can be efficiently received in the concavity and convexity 152 do.

The vibration generator 230 provides vibration to the anti-cohesion pipe 210 to restrict the powder from adhering to the inner wall surface when the aerosol passes through the cohesion prevention pipe 210 and to prevent the cohesion.

If the supply plate 150 rotates in a state in which the gas guide pipe 113 is not operated (the gas is not supplied into the scattering space 116) after the preparation as described above, If the upper surface of the supply plate 150 is adjusted to be in contact with the upper surface of the supply plate 150, the powder P will be present only in the unevenness 152 inside the storage space 115 as shown in FIG.

When the gas is introduced into the scattering space 116 through the gas guide pipe 113 in the state of FIG. 14 and is vertically injected into the upper surface of the supply plate 150, the powder P is scattered and becomes a state as shown in FIG.

That is, a large amount of powder P is stored in the storage space 115. When the powder P is supplied into the scattering space 116 by the clockwise rotation of the supply plate 150, The powder is scattered inside the scattering space 116.

At this time, the amount of the powder P supplied into the storage space 115 can be adjusted by adjusting the shape of the concavity and convexity 152, the rotation speed of the supply plate 150, and the like.

Part of the powder scattered in the scattering space 116 flows into the storage space 115 through the communication part 144. The small and light uniform powder flowing into the storage space 115 flows into the powder discharge pipe 115, And is discharged to the outside of the scattering space 116 through the through hole 114.
